Title: Snatch free air brake - with flow restriction to relay valve and membrane for rapid venting
Inventor: STEINER ADOLF
IPC: B60T15/42
Filed: 1975-11-13
Abstract: the air brake is operated by a control valve (5) which regulates a control pressure signal to the input of a relay valve (3), which in turn connects the brake cylinders (11) to the pressure reservoir. In order to prevent brake snatch a flow restriction (6) is provided between the brake valve and the relay. The flow restriction comprises a small hole in the centre of a flexible diaphragm.
